IA121: NMab Pro Protein A Affinity Resin

Our NMab Pro protein A affinity resin product range offers end users cost competitive and high perfomance Protein A affinity resins. NMab Pro is an agarose based protein A affinity resin developed using innovatively engineered protein A ligand and proprietary technologies of agarose crosslinking, surface extension, and ligand coupling. NMab Pro provides the combination of excellent binding capacity, low non-specific binding that leads to low impurity levels in the elution pool, good pressure-flow properties, and superior alkali-tolerance for stability in the alkaline conditions used in Cleaning-in-place (CIP) and sanitization protocols. Table 1 lists the basic characteristics of this protein A resin:

The engineered protein A in NMab Pro protein A affinity resin is manufactured with animal free raw materials.

NMab Pro protein A affinity resin provides reliable all around performance, low protein A leakage, high binding capacity and a useful effective working range requiring a residence time of at least 3 minutes (equivalent to a typical running speed of 300 cm/hr). It is available in bottled (20% ethanol at 60% slurry concentration) or pre-packed column packaging.
